APPARATUS FOR BLEACI-IING, DYEIN'G, 8w.

Application filed November 6, 1919.

T 0 all whom it may concern:

Be it known that 1, MAX Pon'rzsoH, a citizen of the United States, and aresident of Clifton, in the county of Passaic and State of New Jersey,have invented a newand Improved Apparatus for Bleaching, Dyeing, &c., ofwhich the following is a full, clear, and. exact description.

This invention relates to an apparatus which eliminates or avoidspermanent creases in a piece or string of cloth when dyeing, bleachingor washing the same, and also shortens the process involved.

Another object of the invention is to provide a construction whereinstrings or strips of cloth are automatically changed and refolded in amore or less continuous action during the dyeing, bleaching or washingoperation so that permanent creases will not be formed in the cloth.

A further object of the invention, more specifically, is to provide anapparatus with a roller which may be formed with raised and depressedportions alternately in a sealloped formation, and a spreading orrefolding'member co-acting therewith for causing the cloth to berefolded as it passes over the rollerand thereby prevent the formationof permanent creases during the operation of the apparatus, whether itbe dyeing, bleach-- ing or washing.

roller tothat shown in F ig. 2, the same being on an enlarged scale.

Referring to the accompanying drawings by numerals 1 indicates a supportof any de- SII'GCl lIlHCl for a container 21which is substantiallysegmental in cross section as shown in Fig.1; this shape being providedmerely for the purpose of convenience. Ar ranged in the container 2 is asupply'of liquid which may be dye, a bleaching; compound or washingliquid, said liquid being prepared for acting on the string of clothpassing therethrough for producing the results desired. Arranged abovethe container 2 is a comparatively large driving roller 4 accommodatingthe strips or strings of cloth 5. Any number of pieces of cloth may becaused to move over the roller 4, preferably a' comparatively largenumber so that a large quantity of cloth may be treated when used in anyof the apparatuses .mena tioned, namely dyeing, bleaching or, wash ingmachines, a plurality of pieces of cloth of any length, as for instancethirty yards connected in strings so as to make continu: ous belts. Asmany of these strings are placed on the roller or drum 4 as the samewill accommodate, the strings being ar ranged so that most oftheclothwillbe in folds 6 in the container@ as shown in Fig. 1, while theupper part of the cloth will pass over the drum or rollert, refoldingroller 7 and spreading member 8. A guide 9, similar to that shown inFig. 7 is used for maintaining the strings separate as they leave. theliquid. These guides are made from a suitable frame 10 having partitions11, said frame being secured in place on the container 2'by any desiredmeans, as for instance screws. Preferably a perforated division board 12is provided near the wall 13,. though this is not always necessary. Therefold roller 7 is what may be termed fluted as it is formed withreduced portions or sections 14 and with bulged or raised sections 15alternately for the full length of the roller. This roller carries asuitable supporting shaft to which the sprocket 16 is secured, saidsprocket accommodatinga chain 17 passing over sprocket 18. Sprocket 18is rigidly secured to shaft 19 connected with the drum 4 and with adriving pulley 20. Pulley 2O accommodates a belt 21 which "passes over asmall pullev 22 rigidly secured to the shaft 23 extending through thespreading member 8 to which it is rigidly secured. The member 8issubstantially diamond shape in cross section as shown in Fig. 1 with thepoints rounded and with alternate depressions 24 and raised portions 25arranged in line with the depressions and raised portions 14 and 15. Thebelt, 21 is arranged so as to drive the spreading member 8 at differentspeeds under different circumstances. Usually'when the spreading memberis moving with the goods it moves slightly faster than the goods, butwhen moving in a directionopposite the direction of the movement of thegoods'it moves much slower than the goods. By reason of the chain 17 itwill be seen that the roller 7 moves always in ,one direction with thedrum 4, and by reason of the size of the sprocket wheels 16 and 18 androller 7 has the same peripheral'speed as the drum 4. If desired theperipheral speed of the roller 7 may be slightlymore than the drum 4 soas to assi'st'in spreading as well as refolding the cloth. As the roller7 rotates and as the spreadingmember 8 rotates the cloth will have atendency to move over the reduced portions 14 and 24 upwardly toward theraised portions 15 and 25 and thereby become folded longitudinally at anew'place. When any particular point of the string gets around again tothe roller 7 it will not be folded at the same place that it was before,caused by the tendency of the cloth to climb to the highest point, andconsequently permanent creases will be prevented. After the variousstrings 5 of cloth havebeen arranged imposition the apparatus is started and the strings are gradually moved through the liquid continuouslyfor any desired length of time, as for instance from one hour to siX oreight hours, according to the liquidused, the cloth and othercontrolling circumstances. The apparatus may be driven by anysuitablesource of power which is preferably connected to the driving pulley 26secured to shaft 19.

In Figs. 3 to 6 inclusive will be seen a slight ,modified form of theinvention in which the different construction consists in the use of aspecial form of spreading means 27. The spreading device 27 consists ina flat section 28 having a scalloped edge 29' for causing a movement ofthe cloth laterally of its direction of travel. To better accomplish.this result the spreader is connected to a rotating disk 30 through alink 31. The disk 30 is securedto shaft 32 which carries a worm wheel 333 meshing with the worm 34. The worm 34 issecured to the shaft 35, saidshaft carrying a sprocket 16 and the re-folding roller 7. In this way asthe drum 4 and roller 7 are rotated, the spreader 27 will be movedbackand forth, said movement being preferably slow compared to the rotarymovement of the roller 7.

In Figs. 8 to 10 inclusive will be seen a further modified form of theinvention in which the modification consists in the use of a modifiedform of spreader 36. This spreader consists of aflat plate or board 37having a plurality of spaced eyelets 38. The board 37 is supported on asuitable frame work 39 by pivotally mounted connecting links 40 and 41whereby as the board 37 and associate parts are moved back and forth theboard will be moved up and down also. The length of the links 40 and 41andthe spacing of the eyelets 38 are such that the center of the eyeletwill move from the center of he enlarged portion 15 to the center of thereduced portion 14 of the roller 7 during the operationof the machine.This back and forth motion of the eyelet will assist the roller 7 inrefolding the string continuously so that the string or cloth will notbe folded twice in the same place and thereby will not form permanentcreases. The means for reciprocating the spreader 36 may be any suitablemeans but preferably it is the same arrangement of eccentric and linkstructure described in respect to Figs-4 and 5 so that it will need noadditional description.

In Fig. 11 willbc seen a preferred form of roller 7. It is, of course,evident that the roller 7 could be turned from one piece of wood orother material, but preferably it is constructed as shown in Fig; 11,wherein there is provided a central base42 which may be wood or other.material and extends for the full width of the vat2. This base isprovided with aswelled section 43 adjacent each bulged or raised portion15. Each of the swelled sections 43 is provided with stepped formations44 and 45 and a central raised portion 46 which receives the centralblock 47, which block is wedge shape. 011 each side of the block 47 anumber of disks 48 are provided, each disk being successively smaller asthey recede from the block 47 so as to produce the rounded or bulgedportion 15. The reduced portion 14 is preferably made from a solid pieceof material, as for instance wood, though if desired it could be madefrom other material. Preferablythe central portion 44 and theblocks47'are secured to the base 42 in any suitable manner, as forinstance by screws or keys, while the disks 48 are permitted to freelyrotate on the stepped formations of'the base. The base 42 may beconnected with a rotating mechanism as shown in Figs. 2, 5 and 10, ormay be held stationary so that the cloth'will rotate the disk. When thebase 42 is held sta- V tionary it is preferably positioned So'flthat thecloth .will first engage the disk near the sharpened endAQ of the block47; whereby as it passes over the disk toward the roller. or

drum 4 it will be spread positively so that it tinuous movement, andmeans for longitudir na'lly. refolding the: cloth each time it passesover said feeding means.
